What is the unique charm of Qinhuai in "Smoke cage, cold water, moon cage and sand, night mooring in Qinhuai near the restaurant" that made the poet fall in love with it?

The reason why the Qinhuai River has become a favorite place for poets is mainly due to the following aspects:

1. The Qinhuai River is located in Nanjing, the ancient capital of the Six Dynasties, and the Nanjing Qinhuai Old City South Historical and Cultural Research Association President Gao Anning said: "The Qinhuai River is the source of life in the birth and development process of Nanjing." The Qinhuai River has not only nurtured Nanjing people for generations, but also nourished the extensive and profound Nanjing culture. Every dynasty that established its capital here was inseparable from the nourishment of the Qinhuai River. As the economic, political and cultural center of a dynasty, it is natural that it attracted countless literati.

2. Celebrity effect. Just like our current star-chasers, in ancient times, literati and poets also had countless admirers. When one of them left his own poem on the Qinhuai River, others would naturally imitate it when they came again. The more poets come, the more people will explore this place. Here, facing the poems left by our ancestors, we can also have a poetry contest with our ancestors.

3. The beautiful scenery of Qinhuai River. The vast Hanjiang River is shrouded in the blurred night, and the misty smoke is even more mysterious under the moonlight. I took advantage of the night to park the boat on the Qinhuai River near the restaurant, and looked at everything in front of me, confused. Like the mortal world.

Whether it is spring, summer, autumn or winter, or the sky is clear after rain, the Qinhuai River always has its unique and beautiful scenery. On the shore or on the boat, there are different perspectives and different enjoyment of beauty.

Perhaps the word lingering is specially used to explain the attraction of the Qinhuai River to poets. How can such beautiful scenery make people leave easily?
